Migrating from C# to Elixir
summary
A warehouse desktop backend migrates from C# Windows Forms + Oracle to Elixir with PostgreSQL and Oban, keeping the Windows front end unchanged; the rewrite isolates work into actor-style processes and reduces crashes while improving throughput and fault recovery. Concurrency jumps from 100 → 1,000 concurrent users on the same servers, latency and crash incidents drop, and hosting costs stay stable. Team adoption relies on tests, CI, teaching, and patient incremental rollout. Oracle → PostgreSQL, Oban for background jobs, isolated processes/actor model.
